Part of a research study, by scientists at McMaster university, which is ongoing into
the influence of drinking milk after heavy weightlifting, has observed that milk helps exercisers burn more fat.
The scientists took three groups of young men 18 to 30 years of age,56 in total, and put them through a strict, fivedayperweek weightlifting program over a 12week period. Following their workouts, study participants drank either two cups of skim milk (脱脂奶), or a soy beverage with equivalent amounts of protein and energy, or a carbohydrate beverage (碳酸饮料) with an equivalent amount of energy.
Upon the study’s conclusion, scientists observed that:the milk drinking group had lost nearly twice as much fat—two pounds—as those in the carbohydrate beverage group, who lost one pound of fat. Those drinking soy lost no fat. At the same time, the gain in muscle was much greater among the milk drinkers than either the soy or carbohydrate beverage participants.
As published in the first stage of the study, the milk drinking group came out on top in terms of muscle gain with an estimated 40 percent or 2.5 pounds more muscle mass than the soy beverage drinkers. In addition, this group gained 63 percent or 3.3 pounds more muscle mass than the carbohydrate beverage drinkers.
“I think the evidence is beginning to increase, ”says Stuart Phillips—the leader of the study.“Milk may be best known for its calcium (钙) content in supporting bone health, but our research, and later others’, can continually support milk’s ability to aid in muscle growth and also promote body fat loss. Milk is the ideal postworkout drink for recreational exercisers and athletes alike.”
